Description

  The present invention relates to a ball game machine which prevents a game ball from being unnecessarily discharged from a ball payout device when not in operation.

Conventionally, for example, a pachinko gaming machine, which is a kind of a ball game machine, has a ball tank arranged on the upper part of a mechanism plate, and the pachinko ball stored in the ball tank is discharged at the lower end of the ball via a ball guide rod. It is supplied to the device. In this ball dispensing device, a ball passage communicating with the ball guide rod is provided, and a ball feeding member that is rotated by a drive motor and discharges pachinko balls supplied to the ball passage one by one in the middle is pivotally attached. (For example, refer to Patent Document 1). When a winning ball is generated, the ball feeding member rotates a predetermined number of times to pay out a predetermined amount of pachinko balls as a premium ball. The paid-out pachinko balls are stored in the upper ball tray in front of the pachinko machine.
Japanese Patent Laying-Open No. 2003-62270 (page 2-3, FIGS. 1 and 4)

  By the way, depending on the pachinko hall, the pachinko ball in the ball tank is not removed after the business is finished and is left as it is until the next day. For this reason, pachinko balls stay from the ball tank to the ball dispensing device and are continuously arranged, and the state-of-the-art pachinko balls are held and held in a plurality of circularly recessed ball receiving portions provided on the outer periphery of the ball feeding member. May remain.

  In such a state, since the ball feeding member is connected to the drive motor and does not rotate freely, the pachinko ball is always paid out by the continuous pachinko ball including the state-of-the-art pachinko ball to the ball feeding member. The ball load to be rotated is working. On the other hand, after the business is over, for example, the obstacle nail planted on the game board surface is adjusted. At this time, the hitting action of hitting the obstacle nail or the transparent plate holding frame attached to the front of the game board is performed. There has been a problem that an impact caused by an opening / closing operation or the like is transmitted to the ball dispensing device, and the ball feeding member rotates unnecessarily due to a ball load to cause the state-of-the-art pachinko ball to be dispensed from the ball dispensing device.

  Normally, in a pachinko hall, the number of pachinko balls circulating in the pachinko machine, for example, the number of hit balls, the number of out balls, the number of winning balls, the number of payout balls, etc. are all computer-managed. For this reason, if a single pachinko ball is accidentally paid out from the ball payout device as described above, this pachinko ball is not detected, resulting in a computer error. This raises a serious business problem such that accurate revenue management is not possible.

  Therefore, the present invention has been made to solve the above-mentioned problems. After the business is over, even after the power is turned off, the pachinko ball is not unnecessarily discharged from the ball dispensing device, so that accurate computer management of the pachinko ball is always performed. It is an object of the present invention to provide a ball game machine that can be used.

  In order to achieve the above object, a ball game machine according to the present invention has a ball guide rod for guiding a game ball from a game ball supply source to flow down, and a ball passage communicating with the ball guide rod. A ball payout device that discharges game balls supplied to the ball one by one by means of a ball feed member that is rotated by a driving means as appropriate, on the side of the ball feed member in the ball passage and the ball guide rod A notch recess is provided on the inner surface of at least one passage wall above the ball feed member and the ball feed member so that any of the game balls in the passage temporarily enters a portion thereof to reduce the ball load on the ball feed member. Consisting of

  The notch recess is preferably a hole penetrating the passage wall.

  In the ball game machine according to the present invention, any one of the game balls in the passage is provided on the side of the ball feeding member in the ball passage and the ball guide rod and on the inner surface of at least one passage wall above the ball feeding member. Since a notch recess is provided to temporarily enter a part of the ball feeding member to reduce the ball load on the ball feeding member, when the ball feeding member is stopped by turning off the power to the ball game machine, the ball feeding member is in the passage. Any part of the game ball temporarily enters the notch recess to reduce the ball load on the ball feeding member. As a result, the ball feeding member does not rotate and the pachinko balls are not unnecessarily paid out from the ball dispensing device, and there is an effect that accurate computer management of the pachinko balls can always be performed.

  When the notch recess is provided on the inner surface of the passage wall above the ball feeding member, the ball load caused by the game ball in the ball passage relative to the ball feeding member is reduced, thereby driving means for rotating or stopping the ball feeding member; For example, the motor can be miniaturized and the entire ball dispensing device can be made compact.

  Further, when the notch recess is a hole penetrating the passage wall, there is an effect of discharging dust in the passage.

The ball guide rods 23 are made of synthetic resin and are formed into two front and rear strips. In FIGS. 3 and 4, these ball guide rods 23 and 23 are the lower half of the whole, and a portion close to the ball payout device 24 is substantially omitted. Bent into a single letter. On the other hand, each upper half part is formed in a substantially linear shape as shown in FIG.

  Then, a predetermined position of each ball guide rod 23, that is, a bent portion 26 (two places in FIG. 3) bent downward, and a notch recess 27 (here, a hole) having a predetermined size on its upper side wall 23a. ) Is provided. Each notch recess 27 remains in the passage above each sprocket 33, which is a ball feed member to be described later in the ball dispensing device 24, and any one of the pachinko balls arranged in a row when each sprocket 33 is stopped. This is intended to reduce the ball load on each sprocket 33 as much as possible by temporarily entering a part of each notch recess 27.

  The position of each notch recess 27 is determined as the position of the pachinko sphere that counts upward from the pachinko sphere placed on the upper surface of each sprocket 33 and that is in the vicinity of each bent portion 26. Each notch recess 27 may be a hole penetrating the passage wall or simply a recess. Further, in the state where pachinko balls are continuously arranged in the passage of the ball guide rod 23, the pachinko balls partially inserted into the notch recesses 27 bear a part of the ball load of the pachinko balls above it, When the pachinko balls below it flow down, the size and depth of each cutout recess 27 are selected so that they are removed from the cutout recess 27 and flow down as they are.

  The ball dispensing device 24 is made of a synthetic resin and includes a box-shaped case 28. The case 28 is divided into three parts by a right frame body 28a, a left frame body 28b, and an intermediate frame body 28c interposed therebetween. Is done. When these are united in the front-rear direction, a supply port 29a communicating with the lower end of each passage of the ball guide rod 23 at the upper end, and a discharge port 29b for discharging pachinko balls at the lower end are opened. , 30 are provided. Each spherical passage 30 has an upper supply side formed in a substantially S shape and a lower discharge side formed substantially linearly.

  A hollow portion 31 opened on one side is formed in the lower portion of the case 28, and an opening 32 opened on one side on the lower side of each ball passage 30 communicates with the hollow portion 31. A pair of sprockets 33, 33 are disposed in the hollow portion 31 such that the outer peripheral edge faces each spherical passage 30 through the opening 32.

  Both sprockets 33 and 33 are provided at both end portions of the shaft tube portion 34 whose both ends are open so as to be perpendicular to the central axis of the shaft tube portion 34, and one end of the shaft tube portion 34 is the left frame body 28 b. It is supported by a support shaft 35 that protrudes from the inner surface into the cavity 31. Further, a stepping motor 37 as a driving means is fixed to the outer surface of the right frame body 28a by a screw 36, and the shaft cylinder is attached to the drive shaft 39 of the stepping motor 37 facing the cavity 31 from the through hole 38 of the right frame body 28a. The other end of the portion 34 is pivotally supported.

  The sprocket 33 has the same shape, and has three blades 40, 40, 40 on the outer periphery at equal intervals, and a ball receiving portion that receives a pachinko ball that is recessed in an arc shape between the blades 40. 41 is provided. Further, the left and right sprockets 33, 33 are out of phase by a predetermined angle along the rotational direction. Thereby, each sprocket 33 rotates, and the pachinko ball is discharged from each ball passage 30 alternately.

  A ball detector 42 is arranged at the lower end of each ball passage 30 to detect a pachinko ball paid out from each ball passage 30. The detected signal is sent to a central controller (not shown), and the rotation of both sprockets 33, 33 is controlled so as to discharge a predetermined amount of pachinko balls.

  As shown in FIG. 5, on the supply side of each ball passage 30, a notch recess 27a having a predetermined size and depth is provided on the inner wall 30a of the bent portion 43 bent downward. When the sprocket 33 is stopped, the notch recess 27a also stays in the passage above the sprocket 33 and temporarily inserts some of the pachinko balls arranged in a row into the notch recess 27a. This is to reduce the ball load on 33 as much as possible.

  Further, a cutout recess 27b is also provided on the outer wall 30b on the discharge side of each ball passage 30 and facing the ball receiving portion 41 of the sprocket 33 stopped at a predetermined position in the same manner as described above. In this case, a part of the pachinko ball received in the ball receiving portion 41 is also received by the cutout concave portion 27b side, whereby the ball load on the ball feeding member 33 is reduced.

  The right frame body 28a and the left frame body 28b are respectively provided with screw insertion holes 44 and screw holes 45 corresponding to appropriate positions, and the right frame body 28a and the left frame body are provided on the front and rear surfaces of the middle frame body 28c. The case 28 is integrally assembled by arranging 28b and screwing the screws 46 into the screw holes 45 through the screw insertion holes 44, respectively.

  The pachinko gaming machine P according to the present invention has the above configuration, and the operation will be described next. Since the front and rear ball guide rods 23 and 23 and the ball passages 30 and 30 have substantially the same structure, the front ball guide rod 23 and the ball passage 30 will be described for convenience. Before the pachinko gaming machine P is in operation, the ball tank 20 is filled with a required amount of pachinko balls, and the pachinko balls B falling from the ball tank 20 pass through the tank rail 21, the curve rail 22, and the ball guide rod 23. It flows into the dispensing device 24.

  Since the sprocket 33 of the ball dispensing device 24 does not rotate unless there is an electrical signal, the sprocket 33 is stopped in this case, and the most advanced pachinko ball B1 in the front ball passage 30 as shown in FIG. Is placed on the upper surface of the blade 40 of the sprocket 33. In addition, the load of the pachinko ball B1 is applied to a position close to the central axis of the ball feeding member 33. Although illustration is omitted, at this time, the pachinko balls in the rear ball passage 30 are in the ball receiving portion 41 located at the top.

  Therefore, when a winning ball is generated while the pachinko gaming machine P is in operation, an electrical signal is sent to the ball dispensing device 24, the stepping motor 37 is driven, the sprocket 33 rotates a predetermined number of times, and a predetermined amount of pachinko ball B is Dispensing from the discharge side of the ball passage 30. At this time, each pachinko sphere B is detected by the sphere detector 42.

  When the daily operation of the pachinko gaming machine P ends, the supply of power to the pachinko gaming machine P is stopped. At this time, as shown in FIG. 5, the pachinko balls B remain in the ball dispensing device 24 and the ball guide cage 23 and remain until the next day. In this state, the ball load of the pachinko ball B continuous above the sprocket 33 is applied to the sprocket 33. For example, the pachinko ball B2 is placed in the ball receiving portion 41 of the front sprocket 33 as shown in an imaginary line in FIG. If it remains, the ball load is also applied to the sprocket 33.

  However, one of the pachinko spheres B continuously arranged in the notch recesses 27 in the ball guide rod 23, here, a part of the pachinko balls B3 and B4 enters the notch recesses 27, and is further upstream than that. Reduce the ball load of the pachinko ball B on the side. Further, a part of the pachinko ball B5 enters the cutout recess 27a on the supply side of the ball passage 30, and the ball load of the pachinko ball B on the upstream side is also reduced. Further, part of the pachinko ball B2 received by the ball receiving portion 41 of the sprocket 33 also enters the notch recess 27b, and the ball load on the sprocket 33 is reduced.

  Thus, a part of each pachinko ball B2, B3, B4, B5 temporarily enters each cutout recess 27, 27a, 27b, thereby reducing the ball load on the sprocket 33. Therefore, for example, even if an impact such as adjusting a failure nail on the game board 5 surface or opening / closing the transparent plate holding frame 12 is transmitted to the ball dispensing device 24 on the back side of the pachinko gaming machine P after the business is finished, the sprocket 33 The ball is not unnecessarily rotated and the pachinko ball B2 in the ball receiving portion 41 is not paid out. In this way, unnecessary payout of pachinko balls is prevented.

  Further, when the notch recesses 27a and 27 are provided on the inner surface of the passage wall above the sprocket 33, the ball load caused by the game ball B in the ball passage on the sprocket 33 is reduced, thereby rotating or stopping the sprocket 33. The stepping motor 37 to be made can be reduced in size, so that the entire ball payout device 24 can be made compact.

  In the present embodiment, the notch recesses 27, 27a and 27b are provided on both the supply side and the discharge side of the ball guide rod 23 and the ball passage 30. For example, as shown in FIG. The cutout recess 27b may be provided only on the discharge side in the spherical passage 30. In this case, the ball load of the pachinko spheres B arranged above the sprocket 33 is applied to the sprocket 33, and the ball load is applied to a position close to the center line axis of the sprocket 33. Therefore, the force to rotate the sprocket 33 unnecessarily. Is relatively small. Therefore, if the pachinko ball B2 receives an impact in the state where it enters the ball receiving portion 41, the influence of the pachinko ball is large, but a part of the pachinko ball B2 also enters the notch recess 27b, so that the divided ball load is reduced and the sprocket is reduced. It is possible to prevent unnecessary rotation of 33 and unnecessary discharge of the pachinko ball B2.

  Further, as shown in FIG. 6B, a notch recess 27a may be provided only on the supply side of the ball passage 30. Also in this case, since the ball load of the pachinko spheres B arranged above the sprocket 33 is applied to the sprocket 33, a force is generated to rotate the sprocket 33 unnecessarily. However, since a part of the pachinko sphere B5 enters the notch recess 27a, the ball load on the sprocket 33 is reduced. Therefore, even if the pachinko sphere receives an impact in the state of entering the ball receiving portion 41, the sprocket 33 correspondingly. Unnecessary rotation and useless discharge of the pachinko ball B2 can be prevented.

  If each notch recess 27, 27a, 27b is a hole penetrating each passage wall of the ball guide rod 23 or the ball passage 30, dust can be discharged therefrom, which is convenient. Moreover, since it is a structure which only makes a channel | path wall depressed, a structure is simple and can also be shape | molded easily.

  Further, the ball feeding member in the present invention has its axis orthogonal to the flow direction of the pachinko ball in the ball passage 30, two blades 40 on the outer periphery, three or four as in the present invention, What is called a sprocket type with five, six or more sheets, or what is called a lead screw type in which outer peripheral blades are spirally formed along the rotation axis, to send a ball It ’s fine.
